W-INDOW' AND WALL VENTILATOR one Kubatzky, st. Louis, Mo. ApplicationJuly 25, 1923, Serial No. 221,189 I 4 Claims.

The present invention relates toimprovements in window ventilators andmore particularly to certain'improvements in window ventilators such asshown in my issued Patents Numbers 1,809,518

. and 1,836,852.

The primary object of the present invention is to provide a ventilatorwhich is adapted to be set in a wall construction such as of brick,glass block, stone, etc.

A further object resides in the improved arrangement for efiecting aweather tight construction when the ventilator is in a closed position.

A further object resides in the novel manner of assembling and retainingthe swinging end shields against displacement with. respect to the mainframe of the ventilator.

A still further object of the invention is to provide a ventilator ofthis character which may be easily constructed from sheet metal andembod'ying a relatively small number of parts.

Other objects and advantages of the invention will become apparentduringthe course of the following detailed description, taken inconnection, with the accompanying drawings, forming a. part' of this,-specification and. in which drawings Figurev 1 is a plan view; lookingat the inner side? of the ventilator shown mounted in a wall, and withportions broken away to illustrate certain details of construction. 7 iV Figure 2 is a vertical section thru the ventilator shown in a closedposition.

Referring to the drawings in detail and'wherein similarreferencecharacters designate corre spending parts thruout the several views, theletter A' maygenerally designate the improved ventilator and B a wallconstruction of masonry in which the ventilator is mounted. "Theventilator A comprises an open frame I adapted tub closed at its innerside by a swinging ventilating shield. I2, and provided at its outerside with a removableperforated screen I4.

The frame Ii], while not essentially so, is preferably formed of sheetmetal and includes a horizontal top wall sheet IS, a sloping bottom wallsheet I6, and two .vertical end wall sheets II suitably secured at theirmeeting ends into an open rectangular-shaped frame Ill. With parti'cularreference, to Figure 6, the forward portion of the top wall I5 is bentupward at a right angle as at I8 providing a forwardly facing stopshoulder extending thruout the length of the frame. Formed along theupper edge of the shoulder I8 is a top moulding I9. The outer edge ofthe top wall I5 is turned up to form a combined stiffening flange 20 andan abutment, for

the screen'l l. Y

The inclined bottom wall It forms a cover for a wooden sill 2| whichextends between the bottom portions of the end walls I1 and this sillmay be securedby suitable fastening elements as at 22 in Figured.Adjacent the forward portion of the wall It the metal is doubled uponitself at two slightly spaced apart points providing upstanding walls orflanges 23 and 24 forming, av trough 2:5. The vertical wall 23terminates slightly short of the end walls I! as shown in over the outeredge of the sill-2| and forms an abutment for the screen I4.

Eaehend wall I1 is first bent inward along way to the outer side of eachend wall, along the inner vertical end thereof, is a side mouldingmember 29 and which extend forwardly of the stop flanges 21 .to providevertical channels 3'0.

. The outer vertical edge of each end wall is bent to-form a flange 3|,and these flanges also form abutments for the screen I4 as shown inFigure 7.

Referring now to the ventilating shield I2, the same comprises a pair ofmetal end shields 32 and a glass deflecting shield 33. The end shields-32are formed of sheet metal and are of one piece construction providinga segmental-shaped body portion 34 having 13, convexly arcuated upperedge provided with notches 35. Formed along the outer edge of each bodyportion 34 is a flange 36, and these flanges, when the end shields arein place in the frame l6, extend toward the end walls Along the inneredge of each end shield, the metal is bent upon itself at slightlyspaced points providing parallel ribs 31 and 38 which form grooves forreceiving the end edges of the deflecting shield 33. Formed also alongthe inner edge of the end shield is an outwardly directed flange 39which is spaced slightly from the outer face of the end shield and formsa channel 40 for receiving the tongue or flange 26 when the shield I2 isclosed. This interfltting of the tongues 28 at each end of the frame,within the channels 40 of the end shields renders the assembly draftproof when the shield is closed as in Figure 4. When the shield is openas in Figures 3 and 5, the flanges 36 will engage the stop flanges 21and limit inward swinging of the shield to its open position.

Depending from the top wall [5 adjacent the upper end of each stopflange 21 is a lug 4| and these lugs co-act with the tongues 28 to formguides between which the end shields slide during opening and closingmovement. As Will be observed in Figuresl and 5, the lugs 4| are ofisetoutwardly for a. short distance from the stop flanges 27, toward theouter edge of the frame l6, thus permitting the right angular flanges 36to he slid between the lugs and stop flanges. Provided at the outer endof the upper arcuate edge of each end shield is a. keeper lug 42, andthese lugs co-act with the depending lugs 4| for retaining the endshields in place with the flanges 36 engaging the stop flanges 21. Theselugs 42, prior to positioning the end shields in the frame l form acontinuation of the flanges 36, and after the end shields are in place,these lugs are bent into the plane of the body portion 34 as in Figure 6so as to extend beyond the flange 36 and engage the lug 4|.

In constructing the one piece end shields 32, the right angular flange36 is severed crosswise adjacent its upper end to form the keeper lug42. After the end shield is slid into place in the frame, the upperportion of the flange which forms the lug 42 is bent for a quarter turnso as to co-act with the lug 4| for retaining the end shields in place.To remove the end shields, the lug 42 may be bent back to the originalposition aligning with the flange 36, thus allowing the lug 42 to clearthe lug 4| In placing the end shields in the frame, the lower portion ofthe flange 36 is first inserted behind the stop flange 21 and the shieldlowered into a position as in Figure 3. The shield is then slidlaterally until the tongue 28 aligns with the groove 40. This is madepossible by the beveled lower portion of the tongue as shown in dottedline in Figure 3. The lug 42 may then be bent into the plane of the bodyportion 34, thus retaining the end shield in place. The end shields areretained against lateral movement at their lower portions by the end-sof the trough forming wall 23. The glass shield 33 may then be slid intothe groove formed between the flanges 31 and 38. A knob 50 is providedcentrally of the ends of the glass shield for imparting swingingmovement to the ventilating shield.

Pivotally mounted upon one of the side mountings 29 is an L-shaped latchproviding a handle and a. keeper arm 52. This keeper arm 52 is adaptedto engage in the notches 35 of the end shield for retaining the shieldin various adshield is fully closed, the keeper arm 52 engages over theinner edge of the end shield as in Figures 1 and 4 to lock theventilating shield in a closed position.

The screen l4 comprises a frame 53 in which is mounted a wire screening54 of suitable character. This screen frame 53 engages the flangesformed about the outer edge of the ventilator frame In and each verticalor side rail of the screen frame is provided with a hook 55 adapted toengage in an opening 56 formed in the end walls These openings 56 asshown in Figures 7 and 8 have the metal offset outwardly above theopening and offset inwardly below the opening so as to properly receivethe turned end portion of the hook 55.

Referring now to the manner of securing the ventilator in the wallconstruction, a lintel 60 of any suitable type extends across the upperside of the wall opening. In the example shown the lintel is of .metal.Embedded in the plastic joint of the wall above the lintel 66 is awooden block 6| for receiving a fastening element, such as a screw orthe like 62 passed upwardly thru the top, wall I5 of the ventilatorframe. The lintel is provided with an opening thru which the screw 62passes. Embedded in the plastic joint of the wall below the wooden sill2| is a wooden block 63 for receiving a fastening element 64 passeddownwardly thru the bottom wall 16 of the ventilator frame. Thus theventilator may be inserted into the wall opening from the inner side ofthe wall and secured in place by the fastening elements 62 and 64.

justed open positions. When the ventilating Secured as by cementing orother means to the inner face of the stop shoulder I6 is a sealing strip10 such as of felt or the like, and against which the upper edge of theglass shield 33 abuts to seal the shield along its upper edge whenclosed. The inner rib 31 of each end shield is cut away at its upper endto allow the glass shield to engage the sealing strip 10 thruout itslength.
